Overview SteelCentral Services Controller for SteelApp (SSC) manages the complete lifecycle of SteelApp products such as SteelApp Traffic Manager (STM). With SSC, the licensing unit is the overall bandwidth allocated; there is no limit to the number of instances deployed. This is a new innovation within the ADC market, and allows much more flexible licensing than has previously been possible.

To achieve this, SSC maintains licensing information about each product under its control, in addition to its own license.

Licensing SSC

In order to run, each instance of SSC needs its own individual license. Each has a unique serial number, used to identify related licenses.

Licensing base ADC functionality

SSC introduces the concept of Bandwidth Packs. These provide a pool of deployable bandwidth from which an unlimited number of STM instances may be drawn (subject to the overall bandwidth limits.)

Each Base Bandwidth Pack adds to this pool, and each deployed instance reserves a portion of it for its own exclusive use.

Any combination of Traffic Manager sizes may be deployed. The only limit is the total deployable throughput capacity defined by the Bandwidth Packs purchased.

Licensing additional functionality

For optional features such as FIPS Mode, you can create similar pools using Add-On Bandwidth Packs. These are drawn down on in the same way as Base Bandwidth Packs, but when you do so, the instance must also be drawing on a Base Bandwidth Pack (to provide the base functionality). There is no requirement to purchase the same capacity of add-on packs as base packs—you can deploy some Traffic Managers with FIPS and some without, as needed by each application.

In the example shown below, a customer has purchased 20Gbps of base throughput (split equally between standard and enterprise functionality) and 5Gbps of FIPS add-on. Three STMs have been deployed:

• 3Gbps standard STM

• 3Gbps enterprise STM with FIPS

• 2Gbps standard STM with FIPS.

The FIPS pool is now exhausted, so no further deployments can include this, but there is plenty of capacity left for deployment of standard and enterprise level ADCs.

SteelApp Traffic Manager Bandwidth Pack functionality Base bandwidth packs are available in Standard Edition and Enterprise Edition, with add-on bandwidth packs available for each. Each bandwidth pack is associated with a specific SSC license, and can be used only in a system which includes that SSC as a part of the SSC cluster. If the SSC fails, the bandwidth packs remain valid as long as the SSC is still within the cluster.

SteelCentral Services Controller for SteelApp functionality

SSC manages the compete lifecycle of SteelApp Traffic Managers. An SSC license includes all SSC functionality:

• Deployment

• Licensing

• Metering

• Inventory management

• Performance monitoring

Evaluation licenses An evaluation order includes an SSC license, and Bandwidth Packs for all STM functionality. During the limited evaluation period, SSC evaluation licenses may be used to manage STMs in a production environment, and STMs licensed in this way may be used to process production traffic.

Production Licenses

Production SSC licenses and bandwidth packs may be used for any purposes, so long as bandwidth packs are used exclusively with the associated SSC license. All licenses are subject to the Riverbed End User License Agreement available at http://www.riverbed.com/license.

Frequently Asked Questions

Where may I obtain licenses from? Evaluation and production license keys may be obtained from your Riverbed partner.

How does SSC support high availability? SSC can be deployed to give high availability. In this case, a license key is required for each SSC in the cluster. High availability of the database is the responsibility of the operator, regardless of which form factor is used. Riverbed recommends that all Bandwidth Packs are associated with the license key of a single SSC in the cluster. If that SSC is temporarily unavailable, an associated Bandwidth Pack will continue to be valid as long as the SSC Is a member of the cluster.

What are the latency and bandwidth requirements for the network between an SSC and its STM instances? When all features are required (deployment, metering, monitoring), SSC needs network links with a link latency of 10ms or less and bandwidth of 100Mbps or greater to support scales up to 5000 instances.

When used purely for instance licensing (i.e. licensing non-managed instances), SSC needs network links with latency of 400ms or less to support scales up to 5000 instances.

What happens to my licensed SteelApp Traffic Managers when no SSCs are contactable? If instances are stopped and restarted (e.g. due to a failure) while no SSCs are running and have licensing enabled, the restarted instances will be unlicensed until a SSC becomes available for licensing. It is recommended that SSC is deployed in a HA cluster arrangement to avoid this situation. If instances remain running while no SSCs are available for licensing, they enter a 'grace period' (normally six weeks) and maintain their licensed features until that grace period expires, after which the become unlicensed (and fall back to developer mode).

What are perpetual and subscription licenses? You can license Riverbed SteelApp bandwidth packs on either a perpetual or subscription basis:

• Perpetual licenses provide a perpetual (non-expiring) license key that may be used up to the licensed limit. Support and software upgrades are not included with a perpetual license. This can be obtained by paying an annual support fee.

• Subscription licenses allow you to use the software for a period of time (the ‘term’) and oblige you to pay a subscription fee up front for that term. Subscription licenses include support and maintenance for the duration of the subscription.

Can I run SteelApp Traffic Managers in developer mode? Developer mode is not available for STMs managed by SSC. There is no developer mode for SSC itself. To use a low capacity, non-production SteelApp Traffic Manager, you should deploy independently of SSC. Alternatively, use the granularity offered by SSC to provision a suitably sized instance—with a single 5Gbps license, you could provision 5,000 independent 1Gbps traffic managers.

What limits are there on performance? At deployment time, the operator specifies the maximum capacity of the STM instance. The performance rating applies to outgoing bandwidth (in all directions), after content compression.

Connections will not be dropped unless outbound traffic greatly exceeds the bandwidth capacity for a sustained period of time, when no data can be transmitted before the client or server timeouts expire.

The host hardware must be adequately specified in order to deliver the desired performance.

STM instances managed by SSC are unlimited in SSL performance, up to the deployed bandwidth.

I plan to resell traffic management services. Is this the licensing model I should use? A different licensing model is used for organizations who resell SSC based traffic management services. These organizations, termed Cloud Service Providers by Riverbed, are subject to a separate Service Provider agreement. If you fit this description, please contact your account manager for details.

What happens when a license expires? Perpetual licenses do not expire. Other licenses issued by Riverbed will have an expiration date.

Once a Bandwidth Pack’s expiration date has passed, there must be sufficient capacity in the remaining bandwidth packs to service all deployed instances. If there is not, all instances will drop into unlicensed mode.

Other licences The zero-cost licenses that Riverbed issues for non-production use can continue to be used at no cost unless Riverbed has terminated the relevant license or developer program.
